Patent GB-928624-A (GB)
Title: Organic metal complexes and a process for the manufacture thereof
IPC: C07F9/90
Filed: 1961-07-25
Abstract: The invention comprises the organic metal complexes of a racemic or optically active 2,3-dimercapto-succinic acid wherein one or both hydrogen atoms of the mercapto groups is or are replaced by arsenic, antimony, bismuth or mercury, and the alkali- and alkaline earth-metal salts thereof, and the preparation of these compounds by reacting a racemic or optically active 2,3-dimercapto-succinic acid or an alkali- or alkaline earth-metal salt thereof with an oxide, hydroxide, or acid salt of arsenic, antimony, bismuth or mercury in a liquid reaction medium. The alkali- and alkaline earth-metal salts may be formed by reacting the required free acid with an alkali- and alkaline earth-metal base or oxide such as an alkali metal hydroxide, bicarbonate or carbonate or an alkaline earth metal or oxide or hydroxide.  In an example a complex of the formula [HOOC-CH(S-Sb/3)-CH(S-Sb/3)-COOH]3 and sodium, potassium and calcium salts thereof are prepared.  Therapeutic compositions suitable for oral or parenteral administration in solid form (tablets, dragees, suppositories or capsules) or in liquid form (solutions, emulsions or suspensions) contain as the active ingredient an organic metal complex defined above.  Rac-2,3-dimercapto-succinic acid is prepared by dropping thioacetic acid into a mixture of hydrochloric acid in ethyl acetate and the monopotassium salt of acetylene dicarboxylic acid, separating the resulting water and ethyl acetate layers, concentrating the water layer, adding petroleum ether to the water layer to precipitate rac-2,3-diacetylthio-succinic acid, and treating this acid with sodium hydroxide.  The racemic form of the acid may be resolved into its optical isomers.  By concentrating the ethyl acetate layer referred to above it is possible to precipitate mesco-2,3-diacetylthio-succinic acid.

Title: Electronic telephone network
IPC: H04L25/02
Filed: 1976-06-29
Abstract: 1532889 Substation circuits, anti-sidetone circuits INTERNATIONAL STANDARD ELECTRIC CORP 29 June 1976 [8 July 1975] 27032/76 Headings H4K and H4R In a subscribers telephone operating power is obtained from the line and a signal Vs derived from the operating power is used to control the attenuation of a network 22 between a first transmit amplifier 14 and the two wire line. The signal from the output of network 22 is applied to the line via a circuit 26 and the signals at the input to and output from the circuit are applied to a combining circuit 28 to cancel the transmit signal from the signals appearing across the lines so that only the received signal is applied to the receive amplifier 42. As described the signal Vs derived from the operating potential of the line is fed to two similar variable equalizer circuits 22 and 38 one in the transmit path and the other in the receive path. The equalizers are such that as the line length changes over a normal range the potential Vs varies from 1À15 to 2À2 volts which causes the attenuation to change from a minimum to a maximum value, with the attenuation at high frequencies increasing faster than the attenuation at low frequencies. In addition the transmit attenuator 22 is arranged to increase its attenuation as the potential Vs drops below 1À15 volts, to reduce sidetone on very long lines. An additional attenuator 16 is switched between two alternative attenuation values in accordance with the output of a transmission detector 18 which produces an output signal when a signal is being transmitted and accordingly switches attenuator 16 to a low attenuation condition. In addition the output of detector 18 switches the output impedance of amplifier 26 to a low value, e.g. 300 #, during transmission, so the amplifier provides a substantially constant voltage output independent of line impedance changes, providing virtually constant sidetone attenuation, and to a higher value, e.g. 900 #, during reception so as not to reduce the received signal level too much. The output amplifier 26 is described with respect to Figs. 3, 4 and 5 (not shown) and includes D.C. feedback control to stabilize the operating current drawn from the line, independent of line length, together with a switchable A.C. feedback path to provide the output impedance changes. A polarity guard circuit is described (Fig. 3) including a switched transistor and diode bridge circuit. The amplifier 14, attenuator 16, and transmit equalization control circuits are described with respect to Fig. 2 (not shown).

Title: An improved power transmission unit for vehicles of the four-wheel power transmission type

Abstract: 488,459. Motor-vehicle driving-gear- JACKSON, L. MELLERSH-. (Marmon- Herrington Co., Inc.) Oct. 6, 1937, No. 27077. [Class 79 (ii)] Four-wheel driving-gear comprises a driving or input shaft 19, 21, a driven shaft 23 for driving one pair of wheels, means by which the said two shafts may be directly connected, a second driven shaft 34, 36 for driving another pair of wheels, and a power train between the driving shaft and the second driven shaft comprising an axially-shiftable clutching element 33, which upon over-running of the driving shaft will automatically shift to clutching position and upon over-running of the second driven shaft will shift to declutching position. In the construction shown, the shaft 23 drives the rear wheels through a propeller shaft 25 and the shaft 36 drives the front wheels. The engine 17 drives the shaft 19 through the usual change-speed gear 18. The shafts 23, 34 are coupled by a helical-toothed gear train 26, 32, 33 of which the gear 33 is slidable on its shaft 34 and carries ratchet teeth 40, 41 adapted to engage corresponding teeth on the shaft. Thus, when the gear 33 is driven in one direction, it slides axially, due to the side thrust of the helical teeth, to bring one set of ratchet teeth into action to drive the shaft, and when it is driven in the other direction it slides to bring the other set of teeth into action. Further, in whichever direction the gear 33 is driven the shaft 34 can over-run the gear to compensate for the longer path taken by the front wheels on a curve. The gear train 26, 32 forms part of an auxiliary two-speed gear, the gear 26 being adapted to be driven directly by the shaft 21 through a sliding clutch gear 28 or indirectly through the gears 28, 30, 32. The gearing is enclosed in a casing 20 secured by a bracket 50 to the frame.

The arms 1 may be connected by hooks 10 and links 11 to arms 12 on a shaft 13 which is adapted to be rocked by means of link and lever mechanism for raising the trackmarkers from the ground. The shaft 13 is connected by link and lever mechanism to a shaft 19 carrying the sowing-tubes, so that the shaft 19 is rocked when the shaft 13 is rocked and the sowing- tubes are thus raised when the track-markers are raised. For transport purposes the arms 1 are unhooked from the links 11 and are turned across the machine.
